WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 792,814, dated June 20,1905.

Application filed April 3, 1905. Serial No. 253,578.

To all whom/ it may concern:

Be it known that I, GEORGE BURKHART, a citizen of the United States,residing at National Military Home, in the county of Montgomery andState of Ohio, have invented certain new and useful Improvements inWindow- Sashes, of which the following is a specifica.- tion.

My invention relates to improvements in window-sashes; and it consistsin the constructions, combinations, and arrangements herein describedand claimed.

The objects of my invention are to provide a simple means forconveniently inserting window lights or panes in the sashes and securingthem weather-tight in position.

Referring to the accompanying drawings, forming a part of thisapplication,and in which similar reference-numerals indicatecorresponding parts in both views, Figure is a front elevation of atwelve light windowsash, illustrating one embodiment of my invention.Eig. 2 is a sectional view on the line 2 2 of Fig. 1.

Referring especially to Figs. 1 and Q, 1, Q, 3, and 4 indicate,respectively, the top, bottom, and side rails of a window-sash providedwith three vertical division-bars 5, 6, and 7 and two horizontaldivision-bars 8 and 9. As

shown especially in Fig. 2, the bar 8 is provided with slots 10,extending across and communicating with tapered recesses or grooves 11and 1Q, formed in the cooperating faces of the side rails and verticalbars. The tapered grooves are formed with their inner face 13 parallelwith the plane of the window-sash and with their outer face 14 inclinedfrom the outer edge of the communicating slots '10, the portions of saidgrooves adjacent the slot being formed of greater width than that ofsaid slot in order to provide shoulders 15 for furnishing a secureweather-tight seat for the edges of the window-lights when clamped inplace. A screw 16 extends through each of the slots 1() for securing aclamping-washer 17 against .the adjacent portions of the two lightsinserted in the grooves 11 and 12, thereby providing a simple means forsecurely clamping said lights against the faces 13 of said slots. Itwill be seen that my invention provides a common clamping means for twoadjacent lights which is simple and efficient in construction.

The lower bar 9 is provided with slots 18, extending across andcommunicating with the tapered recesses or grooves 19, formed in thecooperating faces of the side rails and vertical bars, the constructionbeing similar to that just described in relation to the slots 10 andtapered grooves 12. A screw 2O extends through each of the slots 18 inposition to engage the upper portion of a light 21 for securely clampingit in the grooves 19.

From the above description it will be seen that my invention provides areliable means for conveniently securing window-lights in sashesprovided with any number of lights.

Having thus described my invention, what. I claim as new, and desire tosecure by Letters Patent, iS-

1. In a window-sash, the combination of the usual top, bottom and siderails, horizontal bars provided with slots, and vertical bars, saidvertical bars and side rails constructed with tapering grooves extendingin both directions from said slots, substantially as described.

2. In a window-sash, the combination of the usual top, bottom and siderails; horizontal bars provided with slots, vertical bars, said verticalbarsand side rails constructed with tapering grooves extending in bothdirections from said slots, and a common clamping means for clamping thetwo lights inserted in the Agrooves extending from each slot,substantially as described.

' 3. In a window-sash, the combination of the usual top, bottom and siderails, horizontal bars provided with slots, vertical bars, said verticalbars and side rails constructed with grooves extending in bothdirections from said slots, and a common clamping -means in each of saidslots for clamping the two lights inserted in the grooves extendingtherefrom, substantially as described.

4:. In a window-sash, the combination ofthe usual top, bottom and siderails, horizontal In testimony WhereofIaiX mysignature in bars providedwith slots, and vertical bars, presence of two Witnesses.
